Chisage Inverters
Chisage is a manufacturer of PV-hybrid and battery inverters for residential and commercial applications. Their product line includes both single-phase (Jup series) and three-phase (Mars series) hybrid inverters, as well as grid-tie inverters. Chisage inverters support operation with both solar panels and battery storage.
Supported Devices
| Device Type | Variants | Modbus TCP (Ethernet) | RS485 |

Wiring
The SmartgridOne Controller and the Chisage inverters communicate via RS485.
RS485
To connect the Chisage inverter to RS485, use the D-B/485 port on the inverter. The specific pinout may vary, so consult the inverter's manual for the exact connections. A typical RS485 connection table is shown below:
- For correct RS485 wiring: Follow the guidelines for RS485 wiring.
- If the wiring shown in the table below is incorrect, please let us know.
- There is no general consensus in the industry about the usage of A and B for the RS485 polarity, so it may be counterintuitive and opposite of what you might expect for some devices.
| Device | SmartgridOne Controller model OM1 | SmartgridOne Controller model IG8 | RS485-USB converter | RS485-Ethernet converter |
|---|---|---|---|---|
| RS485 A | RS485 A | RS485_POS | RS485 A | TX+ |
| RS485 B | RS485 B | RS485_NEG | RS485 B | TX- |
| GND | RS GND | GND | Not available | G |
Consult the specific manual for your Chisage inverter model for detailed wiring diagrams and instructions.
Configuration
The following steps provide a general overview of configuring Chisage inverters. Consult the specific user manual for your inverter model for detailed instructions and safety precautions.
- Initial Setup: Upon initial startup, configure essential system settings such as the grid standard, language, and time zone.
- Parameter Settings: Access the parameter setting menu, typically through the inverter's LCD touch screen or a dedicated mobile app. Navigate through the menu using the provided buttons or touch controls.
- Battery Settings: Configure battery parameters to match your battery type and specifications. This includes settings such as battery capacity, charging voltage limits, and discharging voltage limits.
- Grid Settings: Configure grid parameters to comply with local grid regulations. This includes settings such as voltage limits, frequency limits, and power factor.
- Smart Load Settings (if applicable): Configure settings related to smart load power, such as the conditions for enabling or disabling power to the smart load based on battery SOC or voltage.

- You MUST give each device on the RS485 bus a unique address. Check the manual of the device on how to do this.
- Use lower addresses first (1, 2, ...) because the SmartgridOne Controller will find them faster!
- For each device, it is generally recommended to stick with the factory default baud rate, parity, and stop bits. The SmartgridOne Controller will scan on those first.
